DOMESTIC HOT WATER SUPPLY SYSTEM Filed June 1927 Patented Feb. 11, 1930 UNITED STATES PATENT OFFICE 'rnomAs WILLIAM TAYLOR, or Yonx, ENGLAND DOMESTIC HOT-WATER SUPPLY SYSTEM Application filed June 4, 1927, Serial No. 196,528, and in Great Britain 'June 15, 1926.

This invention relates to domestic hot water supply systems of the kind wherein a common hot and cold cistern or tank is connected by flow and return pipes directly to the 5 pressure boiler and in which the cold water supply to said cistern or tank is connected by a pipe to the return pipe leading to the pres sure boiler, the chief object being to enable the tank and fittings to occupy a minimum of space without diminishing the capacity of the tank. It has previously been proposed to provide a main flushing tank of substantially triangular shape in plan, adapted to fit into the corner of a room.

According to the invention the tank is adapted to be fitted into the corner of a room and permit of the pipe connections being arranged to the rear of the tank and within the corner.

understood and readily carried into effect, the same will now be more fully described with reference to and by the aid of the accompanying drawings, wherein Figures 1, 2 and 3 are respectively a front elevation, vertical section, and a plan view of the hot and cold water apparatus constructed and arranged according to the invention.

Referring to the drawings, the tank 1 is made of triangular shape in plan and is rounded at the rear so that, whilst capable of being fitted snugly into a corner, the rounded or curved rear wall leaves sufficient space for the various pipe connections to pass down the back or in rear of the tank 1 close to the wall (see particularly Figure Thus, the cold water supply pipe 2 is situated at the rear of the cistern or tank 1, and is connected to the ball float valve 3 near the top and rear of the tank 1. The casing of the ball valve 3 is attached to elbow pipe con nections 4 leading through a fixed top corner cover plate 5 situated at the rear of the cistern 1, said elbow pipe connections l being secured together by nut and screw 6 at the top of the tank 1. The outlet of the casing of the ball valve 3 leads into a vertical dependingpipe 8 for supplying cold water to the boiler (not shown), said pipe 8 extending In order that the invention may be clearlyto and depending at its lower end over a circulation fitting 9 at the bottom of the tank, said fitting 9 being adapted to permit of circulation between the tank 1 and the/boiler when no water is being drawn from the tank 1. Water is fed from the tank to a suitable boiler (not shown) through pipe 10 connected with the aforesaid fitting 9 and the water heated in the boiler returns to the tank through pipe 11. These pipes, as well as the 69 cold water supply pipe 2, are arranged in the space between the rear end of the tank and the corner of'the room so that they are concealed.

Normally water circulates through the tank, the pipe 10, theboiler and the pipe 11 the heated water being retained in the tank and withdrawn therefrom, as desired, through a hot water supply pipe 12 which extends upwardly from the bottom of the tank 1 to about two-thirds the depth thereof, passes rearwardly to the corner. The tank 1 which is mounted in the upper portion of the corner of a room, is supported by two bearer plates 13 which at their extremities are built into the adjacent walls 14: (see particularly Figure 3). The tank 1 has associated with it a wooden or other casing or framework adapted to afford a cupboard or cupboards 15 beneath the tank 1, whilst the top of thelatter is fitted in addition to the top corner plate with a loose lid or cover 16 having handles 17 for removing or replacing the lid or cover 16, over the tank 1. The cupboard 15 which is of similar triangular shape in plan is fitted with shelves 18 and vertical sliding doors 19 so as to avoid occupying undue space, and the said sliding doors 19 may have mirrors fitted thereto. A loose front 20 is fitted to the framework of the cupboards 15 so as to cover in the tank 1, but permit of ready access thereto as and when required from time to tune.

The invention is particularly applicable for houses where the rooms are small and space is therefore a consideration although for economy, cheapness, compactness and general appearance, the improved system may with advantage be universally adopted.

The operation of the system is like those heretofore in use. B the action of the float controlled valve 3 co d Water is supplied to the tank from time to time to to replace hot water drawn therefrom through the pipe 12. The Water circuating through the pipes 10 and 11 and the boiler is heated and withdrawn as needed through the pipe 12.

The upper end of the hot water supply pipe 12 is above the level of the upper ends of the pipes 10 and 11 so that it is impossible to drain the tank through the pipe 12 and a sufficient body of water to maintain circulation through the pipes 10, 11 and the boiler will always be present even if the cold water supply through pipe 2 should be interru te 'l I c aim 1 1. A domestic hot water supply system comprising a tank having top, bottom, front and side walls, the latter arranged at an angle of 90 to each other so that the tank may be closely fitted'in a corner of a room with said side walls parallel to or in contact with the room walls, and the said side walls being so connected at the rear of the tank as to provide between the tank and the apex of the corner formed by the room Walls a space to receive a vertically extending pipe or pi es of the system.

2. in a domestic hot water supply system, the combination with the corner walls of a room, of a tank having its sides arranged in parallelism with said Walls, an article support including side members and a shelf supported thereby, positioned below the tank with the sides thereof in vertical alignment with the sides of the tank, both the tank and said su port being slightly spaced from the apex o the room corner, and a water supply pi e for the tank and circulation and draw- 0 pipes connected with the tank, all having vertically extendin sections positioned within the said space etween the apex of the corner of the room and the tank and support.
